Ectopic and extranumerary parathyroid glands location in patients with hyperparathyroidism secondary to end stage renal disease.

Unlabelled: Supranumerary or ectopic parathyroid glands are the main cause of persistent hyperparathyroidism (HPT) in patients with end stage renal disease (ESRD) submitted to parathyroidectomy (PTx).

Purpose: To evaluate the prevalence and location of parathyroid glands in these patients.

Methods: Thirty-five patients with ESRD and severe secondary hyperparathyroidism (HPT2) had been submitted to total PTx at HUCFF from December 2001 to July 2005.

Surgical approach and clinical outcome of a deforming brown tumor at the maxilla in a patient with secondary hyperparathyroidism due to chronic renal failure.

Brown tumors are relatively uncommon but they are serious complications of renal osteodystrophy. We describe a 31-year-old woman with end-stage renal disease who had undergone hemodialysis for nine years and developed severe secondary hyperparathyroidism and a maxilla brown tumor despite increasing doses of oral calcitriol and calcium carbonate. The fast increase of the right maxillary bone tumor led to indication of parathyroidectomy (PTx).
